Comments

This biopsy from a 75 year old woman was submitted to rule out a basal cell carcinoma. The concentric complex polarization pattern is most consistent with organic material, such as plant matter or splinter. Fungal infections (e.g. dematiaceous organisms) may occur at these sites.

Description

The object polarizes, highlighting the concentric rings.
